  • Method for detecting single postal covers and postal covers stuck together in a mail sorting machine
    Patent number: 7446278
    Abstract: The method of detecting single postal items and multiple overlapping postal items in a postal sorting installation consists in analyzing images (5) representing postal items (6) viewed from in front, and in applying to each image an outline-extracting process (10) in order to recognize items (6) having an outline (10) of substantially constant height as being single items. In this method, the reliability with which single items is detected is improved, and the digital image used for analysis purposes can be the digital image which is also used for optical character recognition processing in the postal sorting installation.
